The first funcion let the user to register/subscribe the target's new personal data, about what did you want to rewrite.
You could change anything, from physical (height, hair color, gender and so on), mental (hobby, personality, and so on) to background (age, family members, weakness, education level, household income and so on) and anything.
This function's introduction told that it could help to avenge or just remake the target.
You could change the retaliation object in any way you wanted or you might change someone you hate into a different person (might be someone you could accept).
Since this function could change someone's background, if you did not like one of your family member, you could do more than just change he or she into someone you could accept, you could change your family background at the same time, such as having you owned a car or became living in a rich family.
I was a member of the zetaboard old forum.
I do not know why I could not register at the no-ip forum before, only it was possible now.
